I have only done a few steel posts over the years. When we did, the concrete was already in the hole (most of it , probably 90%). It was a pain, but forced the pipe down into the concrete by wiggling, pounding, and any means to pull it down. They were pretty stable at that point, but would use 4 boards around it angled at the base. Just used duct tape wrapped around the boards and pipe. They were used for gates, so had to be relatively straight and plumb.
Thanks, Ted, I'd thought about doing it that way, but in this case, each pipe is either 10' or 12' long, and would need to be driven into the concrete 5'. But the biggest concern is that the rails being supported require fairly accurate positioning of the posts, both laterally and vertically. I can fudge the vertical by leaving the posts long and "adjusting" them with a power band saw once the concrete sets, but if they're off laterally, the rails won't run straight. So I was hoping to get all six of them set before pouring any concrete, using strings strung between stakes to ensure that they are all in the correct position.
I also gave some thought to an initial pour of concrete to pre-set the height, with a couple pieces of rebar left sticking up to tie them into the rest of the pour. Just not sure how to reach down into that hole 5' to place the rebar.:confused2:
